How did the social structure in Japan differ from the social structure in China?
Archy [21]

Answer:

China is a multi-ethnic group country with a vast territory. You may even find specific differences between a Beijinger and a Shanghaier.(In general, the former is more forthright and the latter is more gentle) The discrepancy of climatic and geographical environment caused the difference of culture and living habits. The economic and political imbalances bring about the the character difference of local residents. Therefore, it is difficult to find a general feature of Chinese. Japan, on the contrary, is relatively small. When you watch the weather forcast, you will find that there is little difference from Tokyo to Kyoto. To be honest, I have never went to Japan, so I only get the picture of Japanese from books and mangas. In my onion, most Japanese are strict and elegant. They make brilliant mangas and games! I am willing to make friends with them.

Moreover, for historical reasons, China has complex and chaotic ideology. On the surface, China is a socialist country. Nevertheless, most people in this nation do not believe in socialism at all----instead, they believe in themselves, their families and their friends. People fear the great power of the government. However, the government is not that bad. I want to call it the combination of state monopoly capitalism and feudal aristocracy. There are authentic free markets in China. One can find good opportunities and make a living if he or she obeys the rules.

Since ordinary people like me are unable to go into politics, we can just focus on our own lives. We desire tremendous money, big houses, beautiful cars and so on. Yes, it is money worship or power worship (money can make power, and power can make money). People with money and power have great priviledges. The priviledge is magic! You can get anything you want more quickly with this magic. I am an ordinary student with an ordinary background, nut I know that if your father is a government officer or rich merchant, you will definitely have a bright future unless you deliberately ruin yourself (I feel strange! The rich second generation always do so! ) Justice and equity never exist in China. In other words, justice and equity only belong to a few of people. We have to try hard to avoid being losers. It is pathetic to be a loser---girls are unwilling to hang out with a loser!

Lets discuss more deeply. China once had splendid culture, especially when it was going through Tang Dynasty. In that time, Chang'an is the most prosperous city. Japan had sent many students to Tang Empire to study Chinese politics and culture. Japannese not only learn the ancient culture, but also preserve them on the base of improvement. Thanks Japan! We can now appreciate the beauty of Chang'an in Kyoto. However, you know, Chinese people desire power and money. They always fight with each other for power(not for glory) throughout the whole history. I really feel shamed. Chinese almost never work as a unity. I hope we can chage from this generation. We will never fight for our own, but embrace the whole world. We are family, we are one.
